We successively introduce new catalytic centers through click reaction into MOFs and modify their environment by addition of lipophilic groups. The resulting bifunctionalized MOF provides an optimized balance between basicity and lipophilicity and shows outstanding performance for the transesterification reaction.

group exhibits an extended antimicrobial spectrum including anti-pseudomonal activity and high stability to renal dehydropeptidase-I (DHP-I)1}. From the structureactivity relationship studies, we found that the basicity of the C-2 side chain is important for exhibiting antimicrobial activity especially against Pseudomonas aeruginosa by supporting good permeability through the outer membrane(OM)...

Submerged arc welding is preferred over other methods of welding because of its inherent qualities like easy control of process variables, high quality, deep penetration, smooth finish, capability to weld thicker sections. Since the development of submerged arc welding process, welding engineers are striving for reduction in welding cost without compromise in the performance of the weld. Flux u...

For example, in the self-ionization of water we see that two water molecules collide to react and form a hydroxide ion and a hydronium ion. Each reaction begins first by an electrostatic attraction between an electron rich and an electron poor region of the reactants. Hydrogen bonding occurs between the electron deficient hydrogen of one water molecule with the electron rich oxygen of another w...

Few reports exist on the effect of basicity refining slag inclusions in 15-5PH stainless steel and its removal efficiency. In this study, effects various basicities formation efficiency molten were investigated. To investigate chemical makeup non-metallic liquid steel, laboratory experiments thermodynamic calculations conducted CaO-MgO-SiO2-Al2O3-CaF2 with steel. samples that had reacted high-b...

Aminoglycoside antibiotics interact with seemingly unrelated families of RNA molecules. They bind to 16S ribosomal RNA and interfere with the decoding mechanism by distorting the codon-anticodon recognition.1,2 Similar aminoglycosides specifically inhibit self-splicing group I introns3 and the hammerhead ribozyme.4 Recently, these antibiotics have been found to competitively block the binding o...

Ce-modified mesoporous silica materials MCM-41 and SBA-15, namely 32 wt % Ce-Si-MCM-41, 16 wt % Ce-H-MCM-41 and 20 wt % Ce-Si-SBA-15, were prepared, characterized and studied in the selective preparation of trans-carveol by α-pinene oxide isomerization. The characterizations of these catalysts were performed using scanning electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorpti...
